Here is the article:

It looks more like an attempt to push CBS' stock price skyward than it does
a foreshadowing of merger to come, but stranger things have happened.
Noted in the article, though, are these interesting tidbits:
Sumner Redstone, majority stockholder in CBS, has assigned his shares to a
board of trust management system upon his death. That board will include
the Viacom CEO Philippe Dauman and Redstone's daughter, but it will not
include Les Moonves. However, Moonves is expected to become the CBS
chairman of the board when Redstone dies.
The article also notes that Moonves' employment contract (President and CEO
of CBS) ends in 2017 and Jeffrey Bewkes' contract (President and CEO of Time
Warner) expires six months later.
